(1)     Fully dilutive effect of stock options and warrants on per share
        amounts for the year ended December 31, 1994 were antidilutive. 
        Accordingly, fully diluted per share amounts were not presented
        in the Company's consolidated statements of operations.

(2)     Fully dilutive effect of stock options and warrants on per share amounts
        for the years ended December 31, 1996 and 1995 have not been presented
        in the statement of operations since any reduction of less than 3% in
        the aggregate need not be considered as dilution.
